Effects of a Text Message-Based Lifestyle Intervention on HbA1c and Health Behaviors in Older Adults with Prediabetes.

HbA1c, waist circumference, and fasting blood glucose decreased significantly in both the intervention and control groups over the six-month study period.

• Reductions were statistically significant in both groups (p < 0.05)
• Both groups were assessed at baseline and after the six-month intervention period
• The control group was advised to maintain usual daily routines, yet still showed these improvements
• Total sample size was 96 participants aged 50 years and older with prediabetes in South Korea

The intervention group demonstrated significant improvements in body mass index, low-density lipoprotein cholesterol, total cholesterol, and milk consumption compared to baseline.

• These improvements were significant within the intervention group (p < 0.05)
• The intervention consisted of text messages delivered over six months covering nutrition, exercise, medical knowledge, lifestyle, and self-reflective thoughts categories
• These outcomes showed between-group differences favoring the intervention group
• The control group did not show corresponding improvements in these measures

Instant food consumption increased significantly in the control group, resulting in a significant between-group difference.

• The increase in instant food consumption was statistically significant within the control group (p < 0.05)
• The between-group difference in instant food consumption was statistically significant (p < 0.05)
• The intervention group did not show a corresponding increase in instant food consumption
• This finding suggests the text message intervention may have helped prevent dietary habit deterioration

The frequency of late-night eating increased significantly within the control group over the six-month period.

• The increase in late-night eating frequency was statistically significant within the control group (p < 0.05)
• This worsening of eating behavior was not observed in the intervention group
• Late-night eating was assessed via the Korean Health Habits Questionnaire
• This finding suggests the text message intervention may have helped maintain healthier eating schedules

A randomized controlled trial with two parallel groups was conducted among 96 older adults with prediabetes in South Korea.

• Participants were aged 50 years and older with prediabetes
• The study was approved by the Institutional Review Board of Wonju Severance Christian Hospital (IRB No: CR321379)
• The intervention group received text messages for six months; the control group maintained usual daily routines
• Outcomes included clinical measurements, the Korean Health Habits Questionnaire, and quality of life assessments at baseline and post-intervention
• Text messages covered five categories: nutrition, exercise, medical knowledge, lifestyle, and self-reflective thoughts
